It has about a 5000 milliamp hour battery, but this is the Honor

它有大約 5000 毫安時的電池，但這是 honor。

程度副詞

Power 2, yes, it's absolutely a clone of the iPhone, but

Power 2，沒錯，它完全是 iPhone 的複製，但是

It's also thinner than the iPhone and has a 10,000 milliamp hour battery.

它比 iPhone 更薄，而且有 10,000 毫安時的電池。

And this is the world we're living in now.

There are many phones out now with absolutely massive batteries, the size that we only used to see in power banks, but

現在市面上有很多手機配備了超大容量的電池，這種容量以前只在行動電源上才看得到，但

Without actually making the phones any thicker.

But all thanks to a new battery technology called silicon carbon.

這都要歸功於一種叫做矽碳的新電池技術。

So if you're a subscriber, then you've already heard me talk a lot, especially in the past year, about silicon carbon batteries and how great they are and how they're even perfect for certain form factors of phones, like enabling the ultra thin ones like Galaxy S25 Edge and iPhone Air, because they could be super, super thin.

所以如果你是訂閱戶，過去一年來你一定聽我說了很多關於矽碳電池有多棒，以及它們有多適合某些手機外形規格，像是實現了 Galaxy S25 Edge 和 iPhone Air 這類超薄手機，因為它們可以做得非常非常薄。

But still with silicon carbon, have normal battery capacities, but yet those phones didn't have silicon carbon.

但即使是這樣，矽碳電池仍然有正常的電池容量，而那些手機卻沒有矽碳。

In fact, a lot of phones, competitive flagship phones have come out lately that have skipped the silicon carbon battery.

事實上，最近市面上出現很多旗艦手機都跳過了矽碳電池。

Seems like whole companies like Samsung and Apple and Google are just waiting on the sidelines and not touching this new battery tech in any of their phones.

感覺上像是 Samsung、Apple 和 Google 這些大公司都只是在觀望，沒有在他們的手機裡採用這項新電池技術。

So let's talk about these new smartphone batteries.

所以，我們來聊聊這些新的智慧型手機電池吧。

So like I said on the surface, on the surface it would seem like silicon carbon is a no brainer.

就像我說的，表面上看來，矽碳電池似乎是個不費腦筋的選擇。

Obviously you should have it in your phone, especially if you're just looking at the benefits.

很明顯，你的手機應該要配備它，特別是如果你只看優點的話。

They're called silicon carbon because they essentially swap out graphite and use silicon, which can hold way more energy than graphite.

它們之所以被稱為矽碳電池，是因為它們基本上是用矽取代石墨，而矽能儲存比石墨多得多的能量。

So the main advantage is higher energy density.

所以主要優勢是更高的能量密度。

We have phones now with way bigger battery capacities in the same footprint as always.

我們現在的手機，在相同的機身尺寸下，電池容量卻大了很多。

I remember when the new OnePlus flagship came out last January and it made this huge jump from 5,400 milliamp hours to straight to 6,000 milliamp hours by going with silicon carbon.

我記得去年一月，新款 OnePlus 旗艦手機推出時，它就從 5,400 毫安時躍升到 6,000 毫安時，就是因為採用了矽碳電池。

And then later the same year they went to 7,300 milliamp hours.

然後同年晚些時候，他們就達到了 7,300 毫安時。

So it just felt like we are resetting what to expect from a smartphone battery.

所以感覺上我們正在重新定義大家對智慧型手機電池的期待。

But of course, like I mentioned, new Samsung phones keep coming out, no silicon carbon batteries.

但當然，就像我說的，新的 Samsung 手機不斷推出，卻沒有矽碳電池。

New iPhones have been coming out, no silicon carbon.

新的 iPhone 也陸續推出，一樣沒有矽碳電池。

And so people of course are talking about it now.

所以大家現在當然都在討論這件事。

I had some suspicions about why, and a couple other YouTubers have also shared.

我對原因有些懷疑，也有其他幾位 YouTuber 分享了他們的看法。

But I think the main theory was that these are huge companies that are going to ask for massive quantities of stuff from suppliers.

但我認為主要的理論是，這些大公司會向供應商要求龐大的數量。

So with a brand new tech like Silicon Carbon.

所以對於像矽碳這種全新的技術。

You know, if you're Apple, you're going and asking for 10 million of these things for your new iPhone.

你知道，如果你是 Apple，你會去要求為你的新 iPhone 生產一千萬個這樣的東西。

所以如果這是真的，那也說得通。

但話說回來，小米也很龐大，而且

They're using Silicon Carbon and all their flagships and Realme and Honor and Oppo and Huawei and all these companies using tons of silicon carbon in a lot of volume of phones.

他們在所有旗艦機，還有 Realme、honor、Oppo、Huawei，還有所有這些公司都在大量使用矽碳，用在很多手機上。

Meanwhile, Google's over here with the Pixel, not shipping that many phones and not using Silicon Carbon.

相對地，Google 的 Pixel 手機出貨量沒那麼多，也沒有使用矽碳。

So then I recalled I've gotten a few emails in the past year from people in the industry, and

所以我就想到，過去一年我收到一些業界人士的幾封電子郵件，

I won't say which companies they work for, but

我不會說他們在哪家公司工作，但

All smartphone companies and individually, they'd each reached out to me to mention that there are some concerns with silicon carbon batteries.

所有智慧型手機公司和個人，他們都個別聯絡我，提到矽碳電池有些疑慮。

And all their stories matched up about a totally different concern about swelling and longevity.

而且他們的故事都一樣，都提到一個完全不同的問題，關於膨脹和壽命。

Now, I had only seen that in these emails.

現在，我只在這些電子郵件裡看到這個情況。

So I went digging and I reached out to a couple other sources and people that I know at these companies, and

所以我深入調查，並聯繫了幾位我認識的、在這些公司工作的人，

Now that I've heard back from them, I'm actually much more confident that this is the main reason that we're not seeing this tech everywhere in a ton of phones.

在聽到他們的答覆後，我更有信心認為這就是我們沒有在所有手機上看到這項技術的主要原因。

See, one thing about batteries is that as they charge and discharge, they expand and contract a little bit with the heat.

你知道，電池的一大特性是，在充電和放電時，它們會因為熱而稍微膨脹和收縮。

And just like almost any other material, it's why sidewalks have cracks, it's why bridges have expansion joints.

這就像幾乎所有其他材料一樣，這也是為什麼人行道會有裂縫，為什麼橋樑會有伸縮縫。

Basically, every material has to expand and contract a little bit with heat.

基本上，每種材料都會因為熱而稍微膨脹和收縮。

Water is one of the only materials that actually expands while cooling, but

水是少數在冷卻時反而會膨脹的材料之一，但

It expands about 10% in volume while freezing.

它在結冰時體積會膨脹大約 10%。

如果發生得太快，它就會裂開。

So during charging in a silicon carbon smartphone battery, the silicon heats up and absorbs lithium ions.

所以，在矽碳智慧型手機電池充電時，矽會加熱並吸收鋰離子。

And when that happens, the silicon can expand to three, three times its original volume.

發生這種情況時，矽的體積會膨脹到原來的 3 倍。

Like, imagine a sponge that triples in size when wet and then shrinks back down and then over and over again every time it charges and discharges.

就像，想像一下海綿，濕了之後體積會變成三倍，然後又縮回去，每次充電和放電都會這樣重複。

Eventually things are probably going to crack.

You know that meme going around where it's like, oh, if you want to clean the ice off your car windshield really fast, just pour boiling water on it.

你知道那個流行的迷因嗎？上面寫著，哦，如果你想快速清除擋風玻璃上的冰，就倒熱水上去。

But obviously you shouldn't do that because that could literally shatter your windshield because of rapid temperature change thermodynamics.

但顯然你不應該這麼做，因為熱力學的快速溫度變化可能會讓你的擋風玻璃碎裂。

So in the battery, the silicon is actually really finely ground instead of a solid block to avoid the mechanical stresses.

所以，在電池裡，矽其實是經過非常細緻的研磨，而不是實心的塊狀，以避免機械應力。

And the carbon is actually there just to absorb the expansion.

So that's why it's called Silicon Carbon.

所以這就是為什麼它叫做矽碳。

So everyone's messing around and trying to tune it.

Some companies are willing to include a higher and higher percentage of silicon because that lets you get a higher and higher battery capacity in the same space.

有些公司願意加入越來越高的矽比例，因為這樣可以在相同的空間裡獲得越來越高的電池容量。

And so they also have to do their best to manage the inevitable swelling to counteract that.

所以他們也必須盡力控制不可避免的膨脹來抵銷它。

I've actually been told there are certain devices that have a literal steel cage around the battery to prevent it from swelling.

我聽說有些裝置的電池外面會有一個真正的鋼籠，來防止它膨脹。

And then the cracking in this case is potentially some type of internal damage to the battery, which is obviously really bad news.

而這種情況下的破裂，可能是電池內部某種程度的損壞，這顯然是個非常壞的消息。

And worst case scenario is some type of thermal runaway, which obviously nobody wants that happening in their pocket.

最糟的情況是某種熱失控，這顯然是沒人希望發生在自己口袋裡的。

And so you might be thinking, oh, what about all the testing?

所以你可能會想，哦，那所有的測試呢？

Like, that's one of the most common things we hear from these companies is they're always able to verify something like 80% battery capacity after 1000 charge cycles.

像是，這是我們從這些公司聽到的最常見的事情之一，他們總是說在 1000 次充電循環後，能夠驗證大約 80% 的電池容量。

So trying to give us some confidence in the longevity of these batteries because they've actually tested that many cycles, that should make it survive years of regular use.

所以試圖讓我們對這些電池的壽命有信心，因為他們實際上測試了這麼多次循環，這應該能讓它在日常使用中持續好幾年。

But batteries obviously go through a lot more in regular use than just charge cycles.

但電池在日常使用中經歷的，顯然比單純的充電循環要多得多。

Like, like they deal with a lot of outside heat and cold, they get dropped sometimes, there's pressure changes, there's humidity changes, et cetera, et cetera.

像是，它們會承受很多外部的熱和冷，有時會被摔到，還有壓力變化、濕度變化等等，等等。

So testing is really important, of course, but

It's really hard to account for all the variables that a battery might experience over a long period of time.

要考慮到電池在長時間內可能會經歷的所有變數，這真的非常困難。

In one of my conversations, my source mentions that with all the thorough testing going on, getting issues down to a rate of under 1 in 250,000 feels pretty good.

在我的一次談話中，我的消息來源提到，在進行所有徹底的測試後，能將問題率降到 25 萬分之一以下，感覺相當不錯。

Like if you have an error rate of something that's under 1 in 250,000, that's a very rare issue and you should be good to go.

像是如果你有一個錯誤率低於 25 萬分之一，那是一個非常罕見的問題，你應該就沒問題了。

But at Samsung or Apple's scale, if it's tens of millions of phones, that could still not be good enough.

但以三星或蘋果的規模，如果涉及數千萬支手機，那可能還是不夠好。

That could still be a dozen exploding Note 7s like it was in 2016.

那樣可能還是會有十幾支像 2016 年那樣爆炸的 Note 7。

So since there isn't quite enough real world data yet, especially over longer periods of time, some companies are choosing to just sit it out for now and continue developing regular lithium ion batteries.

所以因為還沒有足夠的實際數據，尤其是在更長的時間範圍內，有些公司選擇暫時觀望，繼續開發一般的鋰離子電池。

And you know, remember those companies I mentioned at the beginning that are all not using Silicon Carbon?

你知道，還記得我一開始提到的那些沒有使用矽碳電池的公司嗎？

The Samsungs, the Apples, the Googles, they're all huge companies.

三星、蘋果、Google，他們都是龐大的公司。

But there's also something else they all have in common, which is they all operate or at least have a big presence in America.

但他們還有另一個共同點，就是他們都在美國營運，或者至少在那裡有很大的業務。

And I bring this up because we've talked about this before.

我會提到這一點，是因為我們之前討論過這個話題。

The US especially is a very software focused market.

美國尤其是一個非常注重軟體的市場。

There's all this ecosystem lock in and inherently less hardware competition.

那裡有各種生態系統鎖定，而且本質上硬體競爭較少。

People just want the blue bubbles at this point.

So if people aren't going to buy the new iPhone because of a silicon carbon battery, or they're not switching off of the iPhone because of some other phone's silicon carbon battery, then there is no reason for Apple to take that risk yet.

所以如果大家因為矽碳電池而不買新的 iPhone，或者因為其他手機的矽碳電池而不換掉 iPhone，那麼蘋果現在就沒有理由冒這個險。

But in other markets where people can just use WhatsApp and be happy about it, then there's way more hardware competition and people are willing to switch.

不過在其他市場，大家習慣用 WhatsApp 就很開心了，那裡的硬體競爭就激烈多了，大家也比較願意換手機。

So if one phone has a 40% bigger battery because of some new emerging technology and the other one feels like they're being left behind, people will move to that.

所以如果一支手機因為某種新興技術，電池容量大了 40%，而另一支手機感覺被拋在後面，大家就會轉過去。

So yeah, this will be fascinating to watch it play out today.

所以，今天看這一切如何發展，真的會很精彩。

Still in 2026, silicon carbon batteries are still a bleeding edge technology.

到了 2026 年，矽碳電池仍然是尖端技術。

They're still a little bit riskier and lithium ion batteries are still the safe bet.

它們還是有點風險，而鋰離子電池仍然是穩妥的選擇。

But there's this divide now, so we'll have to keep an eye on how these silicon carbon phones actually age.

但現在出現了這種分歧，所以我們得密切關注這些矽碳手機實際的耐用度。

You know, the first ones came out about three years ago, but

你知道，第一批大約是三年前推出的，但

There's been a lot more out in the real world in the past year.

過去一年，市面上出現了更多。

And so we'll check in, get subscribed and maybe in a year or two we'll have a lot more real world data.

所以我們會持續追蹤，大家訂閱後，也許一兩年後我們就會有更多真實世界的數據了。

We'll check in, we'll see how things are going.

我們會持續追蹤，看看情況如何。
